I asked him how he felt about point sources or radiation in free space, but
got no answer.

Believing in something does not make it so.
Given that it is hard to realize in
practice, but it does have its use in understanding current flow in RF
circuits, the practical problems in implementing a useful ground, and why
we have problems in circuits that we don’t think should have problems.
Simply put, an RF ground is an infinite source or sink of carriers,
delivered or received with minimal delay. That of course is not
realizable,
but understanding why the carriers cannot be delivered or absorbed with
minimal delay helps a great deal in understanding the practical
implementation of circuits we design.
Literally nothing is correct in that paragraph.
